I haven't felt like playing in months except for round-long bursts, but I know that when I did, I was always thinking to myself that extended would be great on Urist.
I stopped playing it because I would flinch in real life every time I saw a security worker/HoP/captain stroll into the bar. My heart would race with fear every time somebody addressed me, especially if in person. I eventually ended up spending most of my time idling in lockers because I didn't feel safe to tab out for a few seconds standing in public. I dropped having a start-of-shift routine (getting clothes and comb and such) because some people preferred not to wait until others had a chance to roleplay for a bit before they started carrying out their objectives. I'd spend a few minutes getting ready and then die.
Even when I was an antagonist myself, I was too afraid to do anything risky, but still obligated to harm the crew, so I did indiscriminate, non-confrontational attacks- breaking windows to space to suffocate those who aren't paying attention and trying to be intimidating. I couldn't fight worth shit if I didn't have a stunning tool/it was versus more than one person because when I get that adrenaline rush, my hands freeze up and go numb, so I can't move my fingers much at all. My preference of not getting involved with anything risky got Pwnzerfaust pissed off at me the moment he called out for help with traitor!Trey Lloyd and I had literally just stepped outside of the station to leave it. He did not take kindly to my non-confrontational traitor policies either, so... yeah. Not going further into that.
If I didn't stop playing, I'd have started having panic attacks again. The game was causing me too much stress.
After I got over my surprise at random announcing the game mode when I came back for a few rounds during August or September, I was actually happy about it, because I remember my sighs of relief when I learned the round wasn't ling or traitor or anything where trust removed you from the round.
So... yeah. I like that people play extended. If I tried to get back into it again, I'd have a lot of fun with it. I like the idea of a calm round.
I, oddly enough, also like what calamity mode sounds like. Everything's fucked to hell from the beginning, so I'd not feel guilty engaging anxious caution mode.
